Which generator is suitable for miner?

 

What is a generator?

The generator, although a side device; But in emergencies, it is known as practical and necessary. A generator is a device that converts mechanical energy into electrical current.

One product of the generator is the generator, which acts like a diesel generator, but on a smaller scale. Accordingly, factories that are leading in the production of generators and diesel generators to facilitate the work of the customer to produce this device. Accordingly, they produced various types of generators in different models.

A generator consists of a generator and a motor that converts the mechanical force generator of the motor into electrical output power using torque, the size of a generator based on the amount of electrical current output, which is KW or KVA. Be different.

Recreational camps, camps and exhibition centers, which are sometimes located outside the area, use generators to supply electricity. Generator is a general term for power generators. A generator is actually a small generator that can be carried and moved.

Types of generators

As mentioned earlier, a generator consists of an electric generator and a motor. Generators are classified according to the type of motor fuel

According to another definition, the generator of a diesel generator has been reduced. Which is used to supply electricity in small places with low capacity.

 

How to use a generator

• Measuring the amount of reactive power consumption and in case of high reactive power, the possibility of installing a suitable capacitor next to the generator will improve its performance. The use of soft starters for electromotor applications and the prevention of their initial start-up impact also improves its performance.

• It is best to use the generator at rated load, and using it at maximum power for long periods of time may damage the generator.

• Timely maintenance and periodic inspections to maintain efficiency and equipment.

• Investigate the possibility of using variable speed motors, especially for impellers and pumps.

• Select high-efficiency generators for long-term operation and in proportion to the required mechanical torque.

• The location of the generators should be such that the heat generated by the motors is easily ventilated.

• Minimize friction of mechanical systems connected to generators.

• Investigate the possibility of using high-consumption motors in non-peak hours of network power consumption.

• If the generator burns out, it is recommended not to repair the defective motor and replace it with a new motor:

• Use the flame to remove the coil in the repair process and thus weaken the core.

• The possibility of damage to the insulation of the teeth of the core sheet.

• Growing coils larger for ease of casting and thus increasing casualties.

• Problems adjusting the position of the end of the coil.

• Increased likelihood of re-burning.

• Reduce engine efficiency.

Starting generator category

Generators can be classified into several forms:

In terms of power consumption to gasoline, diesel and diesel engines

In terms of on and off system to starter and handle generators

Of course, there is a third category, a combination of starter and handle.

The starter type can be easily turned on and off with the start button built into it, and there is no need to handle and turn the engine to turn on.

Starter systems are also divided into single-phase and three-phase power systems. Easy switching of single-phase system compared to three-phase is one of its main advantages.

 

Gasoline generator:

The most widely used type is gasoline. These systems are suitable for long-term operation and their fuel is gasoline.

Depending on the fuel, this product produces carbon monoxide and carbon dioxide, which must be used outdoors, otherwise it will cause suffocation.

 

Gas generator:

This generator is low consumption due to the type of fuel and reduces air pollution and has lower costs than the gasoline type.

Another feature of this device is that it is safe. This type has a longer life than gasoline because it burns gas and removes gasoline.

What should we consider when buying a generator?

When buying a generator, we must first consider the type of fuel. As mentioned, generators are gasoline, diesel and gas burners. Gasoline generators can be easily refueled. Diesel or diesel generators consume less fuel, but it is also more difficult to fuel than gasoline.

The next step is to calculate and consider the power of the generator, which you can obtain from the specifications entered on the device.

Another important thing to consider when buying a generator is the difference in power of the device when starting and running.

Generator noise: Small generators have less noise pollution than other types and are the noisiest type of gasoline generators.

 

What is digital currency or bitcoin?

Digital currency, led by Bitcoin, has been around for several years. The forerunner of digital currencies is bitcoin, which is currently traded in the market at prices in the tens of thousands of dollars per unit.

Digital currencies, such as bitcoins, are given as a gift to the account holder (deposited in his or her wallet) through a process called mining, which essentially puts the computer's processing power in the center of the transaction.

But this mining process performed by the miner requires computers that have very high power consumption. Also, since this process must be done continuously, power outages are not acceptable to the device owner.

In Iran, along with many other countries, digital currency and its extraction have been on the tongues for several years. Alternative power supply or generators in general can be a good way to extract digital currency.

Extraction of digital currencies required; there is a device called a miner that can be set up by an internet line, a miner and a computer or laptop.

At first glance, considering the mentioned requirements, the implementation process seems simple. But along with this issue, the supply and supply of minor devices and then their electricity consumption, production noise and high heat will be a big challenge for those people who want to start it.

These types of devices are mostly used for small light applications. Since the cooling system of this type of generator is air, in the best case, they cannot be used continuously for more than 4 to 5 hours.

The next problem of this type of system is the sound produced in it due to its high period (3000 rpm) and the use of exhaust source in it. If we intend to use this type of generator, it is better to use two devices. So that every 4 hours and in a row, turn on the first one, in the next stage, the second generator enters the circuit and the first one goes off.

 

Diesel generator (diesel) for mining

One of the most widely used generators in the Iranian market is the use of diesel generators or diesel generators.

In this type of generators, first fresh air enters the cylinders, then in the next stage, this air is compressed inside the cylinder, its temperature rises sharply, and in the next step, the fuel is sprayed into the cylinder with high pressure by the injector pump that has been pulverized.

In this type of generators, there is no news about candles, Delco and coils, and its repairs are easier. Compared to benzene and gas generators, more power can be obtained due to the density of diesel fuel.

The main disadvantages of this type of generators are high noise due to its structure and design (compression of air in the cylinder), storage and accumulation of fuel that causes environmental pollution. And extracting currency will be problematic.

However, in some places, due to the lack of city gas, it can be turned on by observing technical factors such as power and appropriate time, which is determined by the manufacturer. Used it.

If we intend to use these generators continuously, it is better that two devices each enter the circuit for 12 hours in order to increase its consumption and efficiency and the life of the devices.

Gas generator for mining

This type of generator is the most suitable and efficient generator for generating electrical power and using it in minor systems.

The availability of natural gas in most areas, low price and cheapness compared to other fuels are the advantages of this type of generators. The general public believes that these gas generators are not capable of continuous operation and cannot be used 24 hours a day for miners.

This theory may be true of gas-fired engines prepared for emergencies, but there are a few key parameters that must be considered in order for the engine to operate under constant operating conditions:

1. The heat produced in this type of engine is much higher than other fuels due to the nature of gas fuel. Failure to pay attention and control this heat for a long time can cause serious damage to the engine.

To solve this problem, the volume of radiators used in the engines offered by the industry is 30 to 40% larger.

The next factor is the use of separate fans from the motor shaft, so that the blower fans in the radiator system are of the electric type, which uses the generator output with the battery output in DC fans. As a result of high cooling efficiency and reduction of generator engine noise.

2. Oil pressure control in gas engines is the second most important factor in engine lubrication. As the temperature increases, the viscosity of the oil will decrease.

The oil used in these engines must be cooled by the cooling oil and re-enter the engine lubrication cycle.

In this type of engine, oil with high combustion temperature and low ash must be used, so the oils used in diesel are not suitable for gas engines and have a lower viscosity.

3. The type of miner load on gas generators is different from other loads.

When testing the operation of the gas generator with thermal elements, no problem is seen. The so-called generator continues to operate with the correct voltage and current. But many times, according to feedback from customers of digital currency miners when generating miners, the generator exhibits abnormal behavior such as voltage fluctuations.

Basically, switching power supply systems have annoying harmonics known as individual harmonics, which cause the generator output waveform to deform other than sinusoidal, generator overheating, power loss, and transmission cables overheating.

For this reason, in order to use the generators optimally to cover the miners, about 30% of the power provided by the generator should be ignored and 70% of it should be used.

On the other hand, the amount of load consumed on each phase of the generator should be completely equal and balanced and sudden overload on the generator motor should be avoided.

In calculating the power of the gas generator engine, the recommendations of the engine manufacturer for operation in constant operating conditions must be taken into account. In the issue of permanent operation of the engine according to the ambient temperature, altitude, humidity and check the correct diagram.

Tips before buying a generator or gas generator for mining consumption that you should know to meet your needs.

In these summer days, when electricity consumption is at its peak, the Ministry of Communications has announced that those who generate digital currency are the largest consumers of electricity in the country's electricity network, and therefore are both a threat to the current situation and an opportunity for the government to earn more.

Given this point, it shows that the Ministry of Energy is looking to organize bitcoin miners, and does not want to. Take this opportunity that nights cannot. It sells electricity production to the consumer because it is not a consumer and also does not want its consumers to feel power outages at peak consumption.

How can we choose the right power generator or motor for our miner devices?

 Each miner device consumes a different amount of power and current depending on its characteristics, which should be checked based on its specifications. Of course, most devices in the Iranian market have a power of about 1.5 kW and a consumption of 7 amps.

If you want to use a generator or generator as an alternative, ie you want to use it immediately after a power outage, it is necessary to provide a control panel next to it so that in the event of a power outage, put it in the circuit. Put.

The use of a generator and its lifespan is directly related to its consumption time. Unfortunately, it is not possible to provide permanent generators or generators of this kind in Iran, and those that do exist are very expensive. Therefore, if you want to use your generator for a long time or even around the clock, you should keep in mind that due to the depreciation of the device, its repair periods are approaching and the life of its consumable parts is greatly reduced.

It is also recommended that if you want to provide a permanent generator, its power consumption should be 70% of the rated power. For example, use a generator with a constant power of 100 kW to consume 70 kW miner (46 miner units)

 

What is the best generator for a miner?

When choosing generators, the following points should be considered:

What is the best and most available fuel for you? Diesel or gas?

• What is the ambient temperature for using the generator? (Ambient temperature has a direct effect on reducing or increasing the efficiency of the device and special maintenance factors have been considered for environmental conditions.)

• Since the miner device must work continuously and 24 hours a day, we must use the best power generating devices so that we do not get involved in depreciation and severe damage caused by it over time.

If you have access to industrial gas, we can calculate the amount of gas you need to introduce the best gas generator, which has a more efficient consumption cost than other devices. And if access to gas is limited, we can introduce and supply the best diesel generators that are more fuel efficient.

Another issue that is important in choosing the power of generators is calculating the power consumption of devices.
